The capacity which some rhizobacteria have for producing compounds of the indole group makes them important for consideration like plant growth promoting rhizobacteria (PGPR). These compounds havean important rolein the development of vegetation. The aim of this study was to evaluate the effect of rhizobacteria producing indole in the development of Capsicum annuum var. jalapeño M. The bacterial strains were isolated from Capsicum sp.and their capacity to produce indole was determined in vitro. Variations in height, diameter of the stem, fruiting and plant appearance,were determined. The bacteria were identified as enterobacter ludwigii, Serratia quinivorans, Lysinibacillus sphaericus, Aeromonas media and pseudomonas poae. The individual application of these bacteria showed no significant difference in any of the variables evaluated. The plants treated with a mixture of these six bacteria did increase the number of fruits produced by C. annuum var. jalapeño M. demonstrating the existence of a synergic effect between the strains (F-7, 47 = 11.144, p = 0.035).
